keratin treatment for your hair

What is a Keratin Treatment?

Keratin treatments repair hair damage by replenishing the hair’s natural protein, smoothing out the cuticles to reduce frizz and enhance shine.

Key Takeaways

  • Keratin smooths frizz, making hair sleek and manageable.
  • Watch out for chemicals like formaldehyde in some treatments.
  • Expect to shell out some cash; these treatments aren’t cheap.
  • Too much of a good thing? Overuse can lead to hair damage.
  • Post-care is key: Use sulfate-free products to prolong effects.

What is keratin?

Keratin is a protein that your hair naturally has. It acts like the building blocks of your hair, keeping it strong and healthy. But when your hair gets damaged from things like heat styling or dyeing, it loses some of its keratin.

Keratin treatments can be great for people with frizzy, curly, or wavy hair who want to make their hair smoother or straighter. However, it’s not a one-size-fits-all solution. If your hair is super fine or already very damaged, the treatment could possibly weigh down your hair or cause more damage, so it’s always best to talk to a professional stylist first.

The keratin treatment process

During a keratin treatment, a hair stylist applies a keratin hair product to your hair and then uses heat (usually with a flat iron or hair straightener) to seal it in. This process can take a couple of hours, depending on how long and thick your hair is.

After the treatment, your hair looks smoother, less frizzy, and easier to manage. It’s like giving your hair a protective coat that also makes it look shiny and feel soft.

To keep your hair looking smooth for as long as possible, it’s recommended to use sulfate-free shampoos and conditioners. Sulfates can strip away the keratin coating faster.

Benefits of Keratin Treatments

Keratin treatments come with a bunch of benefits that can make your hair care routine feel like a breeze, especially if you’re dealing with frizz or dreaming of smoother locks. Let’s break down the perks:

Smoothing Effect

The most noticeable benefit is how smooth your hair feels after a treatment. Keratin fills in the gaps and porosity of your hair fibers, making them less prone to frizz and giving your hair a sleek, smooth appearance.

Frizz Reduction

If you live in a humid climate or your hair just loves to frizz up at the first sign of moisture, keratin treatments can be a game-changer. They help control frizz by sealing the hair cuticle, keeping humidity out and smoothness in.

Easier Styling

Post-treatment, your hair is generally easier to manage. Brushing, drying, and styling can take less time and effort, which is a big plus if you’re always on the go or prefer a low-maintenance routine.

Enhanced Shine

Keratin treatments can increase your hair’s shine. By smoothing the cuticles (the outer layer of your hair), light reflects off your hair more uniformly, making it look glossier and healthier.

Damage Repair

While keratin treatments aren’t a miracle cure for damaged hair, they can help improve its appearance by sealing in the cuticles and minimizing split ends and breakage. This can make your hair look healthier and feel softer.

Long-lasting Results

Depending on your hair type and how well you take care of it, the effects of a keratin treatment can last between 2 to 6 months. This longevity can make it a cost-effective option for those looking to streamline their hair care routine.

Reduced Blow-Drying Time

If blow-drying your hair feels like it takes forever, you’ll appreciate this benefit. Post-keratin treatment, many find that their hair dries faster, saving time and reducing heat exposure.


Keratin treatments can be customized to suit different hair types and goals. Whether you want to keep your curls with less frizz or achieve a straighter look, there’s likely a treatment that can work for you.

Keratin Treatments Side Effects

While keratin treatments can offer a variety of benefits for your hair, it’s also important to be aware of the potential side effects. Knowing these can help you make an informed decision about whether this treatment is right for you. Here’s what you might want to consider:

Chemical Exposure

Some keratin treatments contain formaldehyde or formaldehyde-releasing ingredients. Formaldehyde is a strong chemical that can cause irritation to your eyes, skin, and respiratory system. In salon settings, proper ventilation is crucial to minimize exposure.

Hair Damage

Over time, repeated keratin treatments can lead to hair breakage and damage, especially if your hair is fine or if the treatments are done too frequently. The high heat used during the application process can also be damaging to your hair.


Keratin treatments can be pricey, and since the effects are temporary, maintaining your smooth and sleek look requires regular salon visits every few months, adding to the overall cost.

Risk of Hair Loss

In rare cases, some people experience hair thinning or loss after a keratin treatment. This could be due to the heat and chemicals involved in the process, which might weaken the hair shaft.

Limitations on Hair Styling

After getting a keratin treatment, you’re usually advised not to wash your hair, use hair ties, or tuck your hair behind your ears for several days. This period allows the treatment to set but can be inconvenient.

Change in Hair Texture

While the goal of a keratin treatment is to smooth and de-frizz hair, some people find that their natural hair texture changes over time with repeated treatments. Curls can become looser, and hair might lose some of its natural volume.

Maintenance Requirements

Post-treatment, you’ll need to use specific, sulfate-free shampoos and conditioners to maintain the treatment’s effects and avoid stripping the keratin from your hair. This can add to the overall cost and effort required.

Potential for Allergic Reactions

As with any chemical treatment, there’s a chance of having an allergic reaction to the ingredients used in keratin products. It’s always a good idea to do a patch test or consult with your stylist about the products they’ll use.

Before deciding on a keratin treatment, consider these potential side effects and weigh them against the benefits. If you have concerns, discuss them with a professional stylist who can offer advice tailored to your hair type and condition. They can also suggest alternative treatments that might suit your needs better.


It’s important to weigh these benefits against potential drawbacks, like the cost and the use of chemicals in some treatments. If you’re considering a keratin treatment, chat with a trusted hairstylist to determine if it’s the right choice for your hair type and health.
